One hundred and fifty pounds of the plastic explosive compound C-4 and 250 pounds of undetectable "sheet explosives" — a flexible explosive material that can be hidden in books and letters — were stolen in the burglary, which also included the theft of blasting caps.

The owners of this company should be strung up by their balls! Sheet explosive that can be concealed in letters???? Why even make such a thing? If terrorists took this stuff, it will probably never be found and potentially hundreds of people are already walking dead.
